Researchers Analyze Over 225,000 Tracks from 985 Playlists on Spotify
A recent study conducted by researchers at Aarhus University in Denmark has found that some people prefer to listen to louder and more popular music tracks, including “Dynamite” by BTS, to help them relax and fall asleep. The researchers analyzed over 225,000 tracks from 985 playlists on Spotify associated with sleep, compared to music from a dataset representing music in general. The team aimed to identify whether music chosen for the purpose of falling asleep shares any universal characteristics.
Previous research on the characteristics of sleep music has been limited, according to the researchers. They found that sleep music tends to be quieter and slower than other music. It also frequently lacks lyrics and more often features acoustic instruments. Despite these trends, the researchers also found considerable diversity in sleep music and identified six distinct sub-categories.
Three Sub-Categories of Sleep Music Contradict Common Beliefs
Three of the sub-categories, including ambient music, aligned with the typical characteristics identified for sleep music. But music in the other three subcategories was louder and had a higher degree of energy, the researchers said. These tracks included several popular songs, including “Dynamite” by BTS and “lovely” by Billie Eilish and Khalid.
Despite their high energy, the study authors speculated that popular songs could potentially aid relaxation and sleep for some due to their familiarity. The team said more research is needed to explore this possibility and identify the various reasons people choose different music for falling asleep.
“The study can both inform the clinical use of music and advance our understanding of how music is used to regulate human behavior in everyday life,” the study authors wrote.
The study’s findings are significant because they provide insight into the diverse range of music people use to aid sleep. This research contradicts previous studies that suggest that quieter and slower music is ideal for inducing sleep. It also sheds light on the role of familiarity and personal preference in choosing music for sleep.
The study’s lead author, Dr. Peder Kudsk, said, “It is exciting to see that people use many different types of music to sleep, including music that would not typically be considered sleep music.” He added, “This shows that people have very different preferences when it comes to using music for relaxation and sleep.”
The study’s results have practical implications for individuals who experience sleep disorders or have trouble sleeping. They suggest that people should experiment with different types of music to see what works best for them. It is also an opportunity for music therapists to create personalized playlists for patients to improve their sleep quality.
Sleep latency refers to the amount of time it takes to fall asleep, and a healthy sleep latency period typically ranges from 15 to 20 minutes, according to the nonprofit Sleep Foundation.
This comes after one has done their bedtime routine, such as showering, brushing teeth, and/or meditation, and simply means time spent trying to sleep once in bed.
In conclusion, the study conducted by Aarhus University provides valuable insight into the diversity of music people use to aid sleep. The study found that while sleep music typically tends to be quieter and slower, people also use louder and more energetic tracks to relax and fall asleep. The findings suggest that familiarity and personal preference play a significant role in choosing music for sleep, and more research is needed to explore this possibility. The study’s results have practical implications for individuals with sleep disorders and music therapists, who can create personalized playlists for patients to improve their sleep quality.
